Well the shaking problem is solved. It in fact was just one front lower (rear) control arm bushing rotated 25% off where it should be. In just a few months it was showing wear, and the tech said it was about to crack. I looked at the thing and it was worn. Amazing. Well thanks everyone for your help. Who knew one part could cause all that trauma. And yes, what Steve B. said, go with MB parts with this stuff! It made all the difference.
